This invention relates particularly to a ventibeads'li and stops 4 thereon, the sash 5 slidable lator to be mounted on theoutside of a window etween the bead 3 and stops 4, and the overhead opening having 'a sliding sash therein to function lintel, not shown. The structure described is as a protective baffle over the opening resulting m y known s e d llb n Sliding 5 when the window sash is raised into the open 1 This type Of Window has the sashes Slid- 0 position, permitting the free circulation of air able i a ve eelplane whereby Whenthe sashes thru the ventilator and window opening into are in the p d position, an Opening is formed the area to be ventilated and preventing rain, between P edge of the pp Sash and the water, dust and the like from accompanying the lintel, d a p o m d b ween th bot- 1 air flow, 1 tom edge of the lower sash and the sill.

The edging is preferably formed of sheet rubber secured to the edge of the sheet 13 by a' pressed metal clip 16.

of screen or the like. The screen 18 lies above and extends out beyond the Window frame sill 1, so that air entering the ventilator comes up from underneath. The sheet 13 covers the screened,

bottom of the ventilator and prevents anything striking the ventilator from above from entering the ventilator.

When the lower edge of the sash 5 is raised away from the sill 1, to a point opposite the upper It is to be understood that the ventilator may be installed in a window frame as a complete unit or it may be installed piece-by-piece out of the separate elements of which it is made up.

Having thus described this invention, what I claim and desire to secure by Leters Patent is:

In a window ventilator for sliding windows, said ventilator having a housing of substantially triangular crosssection secured at its opposite ends to the window jambs, the base of the triangular housing being perforated and arranged at right angles opposite the lower end of the window, the side of the housing adjacent the window being open, and the inclined side of the housing being imperforate and being extended from the outer edge of said base upwardly toward the window, a clip on the longitudinal edge of the inclined imperforate side of the ventilator extended alongside the window, and a resilient rubber edging fixedly secured in said longitudinal clip to be resiliently pressed against the sliding window at the top of the ventilator.
